To clean residues
- Imbibe clean cloth.
- Wipe surface to be cleaned with cloth. OR
- Rinse area by pouring neat solution over it, with or without the use of a hog hair cleaning brush. a. Ensure that wash runs off the circuit board along the shortest unencumbered path to prevent redeposit of solvated residues. OR
- (Exceptionally) Immerse component in a container filled with a fresh 824 solution.
- Applications & Usages
Since the 824 is safe for most plastics, seals, ceramics, and printed circuit board components, it is used heavily in the electronics industry. It is great for cleaning printed circuit board components and electronic contacts and connectors. It is also used to clean oxides and grime on audio or video tape heads. It effectively removes light greases, oils, and flux without adding additional residues to contacts, relays, and circuit boards connectors. It is quick drying relative to water. Further, it can be used to wash off more aggressive organic solvents like acetone or toluene.

Technical Details & Test Data
- Compatibility
It is compatible with many plastics, seals, PCB components, paints, rubbers, and plant fibers.
Substrate Compatibility : Consult the 824 compatibility chart for a tentative compatibility list. These compatibility ratings should be considered as tentative due to variations in plastic manufacturers’ formulations and additives, as well as the processing conditions during cleaning.Attention !
Always perform a compatibility test on a non-critical area or a representative test substrate prior to use. Test even if the compatibility chart predicts a high compatibility: modern parts may incorporate undeclared sensitive materials (such as custom plastic blends, custom additives, protective coatings, or decorative coatings).
824 Plastics Compatibility Chart
Plastic type Resistance Epoxy Excellent ABS (acrylonitrile butadiene styrene) Fair to Poor PMMA (acrylic and plexiglass) Poor PVC (polyvinyl chloride) Excellent HD-PE (high density polyethylene) Excellent LD-PE (low density polyethylene) Excellent PP (polypropylene) Excellent PS (polystyrene) Excellent PC (polycarbonate) Excellent Nylon Poor to Severe Note: Rating is given for room temperature only. Heating the solution generally decreases the chemical resistance.
LEGEND
- Excellent = Negligible chemical attack over long exposures
- Good = Slight attack with minor absorption over long exposures
- Fair = Moderate attack with swelling, softening, loss of strength (may tolerate short term exposures)
- Poor = Not recommended due to possible crazing, cracking, discoloration, or loss of strength
- Severe Effect = Decomposition or dissolution after short exposures

Heating the solution generally decreases the chemical resistance.
Attention !
Do NOT use on computer monitors, tablet screens, or eyeglasses. This solvent is too powerful for the coatings used on these devices.
